Motivation is a wide topic that is usually discussed in organization behavior. Every human being requires motivation to continue with a task. Even life itself requires motivation. There are some people who opt to die when they do not have anything in their life to captivate them.
Motivation is very much linked to what one will get at the end. Someone will say, it’s result oriented. The people who sometimes opt to die because of lack of motivation, they first lack anything interesting in life. Everything around seems the same.
In the case where there is no motivation, you can create your own motivation. Set goals to accomplish within a specific time. Make sure you accomplish them. In the process everything around would seem new and worth participating in.
If you are a manager, announce a salary increment or some time off from work. Your employees would be very motivated. This will go in a long way in increasing production.
